1. Optimize the choice of raw materials
Raw materials are the main component of metallurgical core wire production costs, optimize the choice of raw materials is the key to reduce costs.
Reasonable selection of alloying elements: according to the needs of steel, select cost-effective alloying elements. For example, in the process of deoxidation, calcium-silicon alloy can be used instead of pure calcium, which can not only meet the requirements of deoxidation, but also reduce the material cost.
Procurement of high-quality and low-priced raw materials: establish a long-term cooperative relationship with suppliers, and reduce the price of raw materials through bulk purchasing or centralized purchasing. At the same time, pay attention to the international market conditions and purchase raw materials with lower prices at the right time.
Recycling of waste materials: Recycle and reuse the waste materials generated in the production process, such as recycling metal powder, trimmings, etc., to reduce the waste of raw materials.
2.Production process optimization
Optimization of production process can improve production efficiency, reduce energy consumption and material waste, thus reducing production costs.
Improve the structural design of core wire: Reduce the use of outer steel belt by optimizing the structural design of core wire to reduce the material cost. For example, using thinner steel tapes or reducing the thickness of the cladding layer, while ensuring that the performance of the core wire is not compromised.
Increase filler rate: Increase the filler rate of the alloy powder during the core wire production process to reduce the amount of steel strip used. By improving the filling equipment or optimizing the filling process, costs can be reduced under the premise of ensuring the quality of the core wire.
Optimization of heat treatment process: By adjusting the parameters of heat treatment process (such as temperature, time, etc.), energy consumption can be reduced, while improving the performance of core wire and reducing the defective rate.
